Raspberry Pi Smart Vertical Farming Takes Veggies To New Heights (tomshardware.com) 45

Tanay Tanay has developed a smart vertical farming system using a Raspberry Pi 4 as the central controller, with features such as Bluetooth and Wi-Fi support for remote plant monitoring, precise automated watering based on moisture levels, and environmental factor tracking. Tom's Hardware reports: The end result is a Pi-powered system with tons of cool goodies to take your plant care to the next level. Tanay is able to monitor all sorts of environmental factors like how much light is available, how moist the air is, how much water is in the soil, what the temperature is and much more. The icing on the cake is a user-friendly interface that can be used to manually water the plants.

The main board for this project is a Raspberry Pi 4 B. It's connected to an Arduino Nano R3 which is assigned to a specific plant. Some of the sensors confirmed in the design are a soil moisture sensor, an ambient light sensor as well as a water level depth detection sensor. You could always add more or take away modules depending on what you want to do with your vertical farm. For example, a camera could be used to log plant growth progress over time. Tanay explains that ThingSpeak, an IoT platform, was used in the project design.

      I'm wondering how much it costs to run the grow lights for all the levels except the top one.

      • The last report I saw on this idea said it couldn't be made to work without a massive subsidy. It seems unlikely that you can put up a tall building and supply lights and water and compete with someone who bought a chunk of land and uses the sun and rain. Even a big greenhouse must be substantially cheaper.

          That's pretty much what I'd expect, especially with the rising cost of electric service. You might minimize that by letting it be dark during peak hours, but that's an awful lot of idle time you've still got to provide water (which ain't free), not to mention the building.

          Folks with just a homeowner's electric service have zero clue how much a large service costs, let alone how much water goes into produce sufficiently profitable to even think about such a venture. And how few calories you get per dollar of

    The small pumps (specifically these models) and moisture sensors are made since years and sold in the usual places, including Amazon. The code is on github. Bought a kit of 4 and used 3 of them (for much bigger plants, and a much bigger "far" in the end) when I was gone in my last vacation. By the way, the plastic tubes you see fit on the pumps, they won't stay like that forever, the pumps will push them out eventually and of course that sucks if you leave stuff on their own. I'd need to either glue them or put some tiny metal collar on them, if I can find some (maybe a zip tie, or two thin ones might be enough too).

Put some water tight sealant right behind the flared bit, read the directions for how long it needs to cure. While it is curing, put your PVC hose onto the pump well past the flared

    I worked at a vertical (hydroponic) farming start up that raised a couple hundred million in funding, valued at over a billion, unicorn and all that. The controllers in the farms themselves were RPi class machines that talked to Google's IoT service. They were manufactured to order (no video ports, for example), always online via LTE modems, and they were stable and did their jobs well.

        The vertical farm concept is so stupid that I thought it was a joke the first time I heard it.

        Why use expensive urban real estate, electric lights, and pumped water to replace rural farmland, free sunshine, and rain?

        The only plausible saving is transporting the harvested crop, but that is vastly outweighed by transporting water and fertilizer, plus all the commuting done by people who can't live in the city because we built a high-rise farm instead of apartments.

            Speaking as someone who does intensive gardening (as in enough to feed several people vegetables, berries, and such in a 25'x40' area, your answers show you have little experience working with dirt.
            1. Farmland is getting expensive but unless you're planning on investing in kevlar or naurto-dodging bullets, rural land is cheaper.
            2. You're powering those lights with what, mystical fairy farts? Solar panels or grid power cost a lot of money, though I do use small scale solar for microcontrollers
            3. So can any standard greenhouse, and I can arduino control that too... Honestly RasPI4's are massive overkill.
            4. Pest management isn't the insane amount of poison that Greenpeace would have you believe. Maintaining your soil ecology is a first step to avoiding most pests. Growing plants that attract beneficial insects around your garden does a surprising amount to stop pests. For larger rodent pests owl boxes work wonders.
            5. fertilizer isn't measured by acre, it's measured by plant consumption. If you're growing less plants then you will use less fertilizer. If you grow more plants you will use more fertilizer. Most plants (I could get into cover cropping here, but choose not to) deplete the soil. Sustainable farming uses a lot of compost, bone meal, blood meal, feather meal, etc. which are waste products from other local farms.
            6. you still haven't gotten around the HUGE power bill that comes with vertical farming. Making this approach carbon neutral vs row cropping is non-trivial. Farm equipment is run a lot less and pollutes a lot less than you think vs what is harvested. On most row crop farms a field is cultivated, seeded (sometimes both of these are done in one pass), sprayed, harvested, and tilled in a year. That's 5-6 passes of a tractor over a field in a year. Most large row-crop farms are planting swaths of 40-50' width each pass. This means that with the right equipment a farmer on his tractor can plant, fertilize, or harvest, thousands of acres a day. In exchange for running a diesel engine roughly equivalent to that in a Jeep Grand Cherokee diesel, with better pollution controls, for 14 hours 5 times a year, you get 1000 acres of corn...

            Look, I get it, cityfolk are scared of big row crop farms because greenpeace says you need to be scared. Why not go meet a farmer and find out where your food really comes from.

              • This should absolutely be modded up. Lots of chemicals are used in organic farming. Neem oil is used as an insecticide. Lots of chemical alternatives are also used. As I noted I can plant plants that will keep insects out. I may not be able to spray Pyrethrum insecticide but I can plant it! Pyrethrum insecticide comes from a flower called Pyrethrum. Planting it intercropped, or as part of a hedge keeps many harmful insects out.

                That's spending dollars to save pennies. For the cost of running heat grow lamps to illuminate all the plants for the entire growing season, you could ship the crops by jet plane, which is NOT how they actually get transported in the real world, because that would be absurd.
              • Shipping is cheap. Very cheap. Giant climate controlled warehouses are expensive. It's much cheaper and more efficient to ship tomatoes to Minnesota rather than grow tomatoes in giant climate controlled greenhouses in Minnesota. I can only see vertical farming making sense for some easily-perishable ingredients used in elite restaurants, where the cost is of less concern than absolute freshness (and maybe even part of the appeal).

            Only in rare special situations, not in general, not in the long term, and never in the kind of quantity that would ever allow a "vertical farm" setup to meaningfully compete with a traditional agribusiness, even for one growing season.

          With regards to water, the idea is to keep it as closed to close cycle as possible, so you only have to add water that exits the system in the form of harvested plant. You don't just drain it away as it works through the soil (or whatever substrate you're using).

          Vertical farming is completely viable and a number of businesses are doing it successfully.

          However, they are growing high-value crops which don't travel well near the point of consumption.

          The poster child for this type of agriculture (cannabis aside) is salad greens. High end salad mixes are extremely high dollar items. But if you transport them any distance then you inevitably wind up with a lot of waste.

            FWIW, I don't think vertical farming *needs* to be hydroponic. It's just that it developed out of hydroponic farming. But that approach does enable better standardization. (But I think I've also seen intensive cultivation of tomatoes on trays of sand. That's not exactly hydroponic, but it also wasn't a vertical farm.)

        It is only a dumb idea if you're competing directly with a real farm on low cost crops on cost alone. Ever eat a fresh strawberry? They taste MUCH better than anything you'll eat a grocery store because fresh strawberries are delicate and don't keep during transport. A lot of produce cannot be picked in its freshest state as its intended to be shipped across country or across the world.
